An example of a circuit protection device is a fuse. Another example is a circuit breaker.
After a switch the most common safety device is a fuse or circuit breaker
A fuse or a breaker.

Circuit breakers do not use anything, they are a controlling device. They can automatically open the circuit if the current exceeds the current rating and you can manually disconnect the power from the circuit.
The terminology down stream refers to an electrical circuit and where devices are connected into the circuit. In reference to the breaker that feeds the circuit everything is down stream from it. If a GFCI receptacle is added into the circuit as the first device, the GFCI can be wired to allow all of the regular receptacles to be protected down stream from that GFCI. Every device added to the circuit will be down stream from the one that is ahead of it. The only device that will not have something down stream from it will be the last device in the circuit.
Earth wire is meant to protect the user in case there is earth fault in the device or circuit. Only earth wire alone is not sufficient. It needs to be provided with suitable circuit breaker that breaks the circuit automatically.
A device that opens and closes a circuit is called a switch.
to assemble a circuit you just need to connect one end of a wire to the battery and the other to the light bulb ( could be another electrical device) now take an other wire and connect on end of it to the other side of the battery and the other to the other side of the light bulb( or an other electrical device. if your circuit is including a switch this is how you do it: ( you will need three wires for this circuit if you have one electrical device) connect one end of the wire to the battery and the other to the switch.Grab another wire and attach one end of it on the other side of the switch and the other to the electrical device (light bulb). Grab another wire and attach one end of it to the other side of battery and the other to the other side of your electrical device. And there you have it how to assemble a circuit
The device that protects the home from the start of an electrical fire is an electrical breaker or in some older homes a fuse system.
In electrical terminology it is an over current device. This could be an electrical breaker. Another form of an over current device is a fuse.
Fuse, Circuit breaker
The definition of a switch is a device that closes and opens an electrical circuit.

An electrical annunciator is a device that signals when an electrical circuit is being used.
A fuse or circuit breaker will fit this description.
A switch is a device that is used to open and close an electrical circuit that is is connected into.
A series circuit is one in which the current must pass through all the electrical devices in the circuit in turn. A parallel circuit is one in which the current passes through each electrical device on the circuit following separate, independent path from all other devices on the circuit, one for each electrical device.
